Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅

hope this helps :p
Answer:
4 V + 4 (V - 60) = D where D is distance apart after 4 hrs
8 V - 240 = 7304
V = 943 km/hr
and V2 = 943 - 60 = 883 km/hr where second plane is 60 km/hr slower
The area of the enclosed space is given by the equation
(6+2x)² = 169
We can take the square root of both sides, since 169 is a perfect square:
√(6+2x)² = √169
6 + 2x = 13
Subtract 6 from each side:
6 + 2x - 6 = 13 - 6
2x = 7
Divide both sides by 2:
2x/2 = 7/2
x = 3.5
